[0020] When wiring, according to the wiring position of the wire, the frame 7 is moved to drive the adjustment block 6 to move in the adjustment groove 5. After moving to the wiring position, the cable tie is inserted into the U-shaped frame 7. After the cable tie is inserted, it squeezes the positioning component 9. The positioning component 9 contacts the inner wall of the adjustment groove 5, and then the position of the adjustment block 6 is fixed. Then the cable tie is used to bundle the wires to fix the wiring position. The connecting tube 8 is rotatably connected to the adjustment block 6, and then the bundling direction of the cable tie can be adjusted in time according to the direction of the wiring, which is more convenient for wiring operations.

[0021] Example 2

[0022] Reference Figure 1-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. Specifically, a lamp hole is provided inside the lampshade 3 and the lamp hole is opened on the car top plate 1. A lamp is fixedly installed inside the lamp hole to realize the lighting of the elevator car, and the lampshade 3 protects the lamp.

[0023] Specifically, the frame 7 is a U-shaped structure, and the U-shaped structure makes it convenient to insert a cable tie into the frame 7, and the cable tie is used to bundle and fix the wires.

[0024] Specifically, the adjusting groove 5 is a T-shaped structure, and the adjusting groove 5 cooperates with the adjusting block 6 of the T-shaped structure to facilitate the movement of the adjusting block 6 and prevent the adjusting block 6 from falling off.

[0025] Specifically, the positioning assembly 9 includes a movable rod 91, a movable cone 92, a cylindrical cavity 93, a transverse movable cavity 94, a movable hole 95, a positioning rod 96, a spring 97, and a limiting ring 98. The movable rod 91 is slidably sleeved in the connecting tube 8, one end of the movable rod 91 is fixedly connected to the movable cone 92, the movable cone 92 is movably sleeved in the cylindrical cavity 93, the cylindrical cavity 93 is hollow and arranged in the adjustment block 6, transverse movable cavities 94 are opened on both sides of the cylindrical cavity 93, and the end of the transverse movable cavity 94 away from the cylindrical cavity 93 is connected to the movable hole 95, the positioning rod 96 is slidably sleeved in the movable hole 95, one end of the positioning rod 96 slides against the movable cone 92, the side of the positioning rod 96 close to the movable cone 92 is fixedly sleeved with a limiting ring 98, the limiting ring 98 is slidably sleeved in the movable cavity 94, one end of the limiting ring 98 is fixedly connected to one end of the spring 97, and the other end of the spring 97 is fixedly connected to the inner wall of the movable cavity 94.

[0026] After the adjusting block 6 moves to the wiring position, a cable tie is inserted into the U-shaped frame 7. After the cable tie is inserted, it squeezes the movable rod 91 of the positioning assembly 9. The movable rod 91 moves to drive the movable cone 92 fixed at the end to move in the cylindrical groove 93. After the movable cone 92 moves, the positioning rod 96 with the conical surface in contact moves toward the movable hole 95, and the end of the positioning rod 96 contacts the inner wall of the adjusting groove 5, thereby fixing the position of the adjusting block 6. Then the cable tie is used to bundle the wires to fix the wiring position. The connecting tube 8 is rotatably connected to the adjusting block 6, and then the bundling direction of the cable tie can be adjusted in time according to the direction of the wiring, which is more convenient for wiring operations.

[0027] Furthermore, one end of the positioning rod 96 is a hemispherical structure and slides in contact with the movable cone 92. One end of the movable rod 91 away from the movable cone 92 protrudes out of the frame 7 and is protruded to a certain height. After the cable tie is inserted into the frame 7, the squeezing force of the cable tie causes the movable rod 91 to move toward the cylindrical cavity 93, thereby driving the movable cone 92 to move.

[0028] Example 3

[0029] Reference Figure 1-3 , which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When wiring, according to the wiring position of the wire, the frame 7 is toggled to drive the adjusting block 6 to move in the adjusting groove 5. After moving to the wiring position, the cable tie is inserted into the inner part of the mouth-shaped frame 7. After the cable tie is inserted, it squeezes the movable rod 91 of the positioning component 9. The movable rod 91 moves to drive the movable cone 92 fixed at the end to move in the cylindrical groove 93. After the movable cone 92 moves, the positioning rod 96 with the conical surface in contact moves toward the movable hole 95. The end of the positioning rod 96 contacts the inner wall of the adjusting groove 5, thereby fixing the position of the adjusting block 6. Then, the cable tie is used to bundle the wires to fix the wiring position. The connecting tube 8 is rotatably connected to the adjusting block 6, and then the bundling direction of the cable tie can be adjusted in time according to the direction of the wiring, which is more convenient for wiring operation.
